PAPEB-STOCK-ITREATING MAGHIILTE.

.Be' it know'nthat' I, WILLIAM HEizRBonn', a citizen of 'the United States, residing] at Kalamazoo, countyxof Kalamazoo, State of Michigam'have invented certain new and useful Improvements in Paper-Stock-Treat ing Machines, of which" the following is a specification.

' This-invention relates to improvements in paper stock treating machines, I I

My improved stock treating machine is especially designed by me for use in treating old paper disintegrating the .same for use as paper stock, although it is desirable for use in treating other fibrous material designed for paper stock. r

The main obj ects of this invention are: First, to provide an improved stock treating machine which effectively disintegrates or separates the fibers without a grinding action or abrading. I i Second,v to provide ,an improved stock treating machine'which is of very large capacit y. I I

Further objects, and objects relating to structural details will'definitely appear from the detailed description'to follow;

' I accomplishtheiobjects of 'my invention by'the devices and means'described in the following"specification; The invention is clearly defined and pointed out. in thejclaims. A struc'tureqwhich. is a preferred embodiment of my invention is clearly illustrated I I drawing forming a part'of thisspecification, in which-z FigureI i'sa vertical longitudinal section of a paper stock treating machine embodying the features ofmy invention, pai't's be-v ing shown inelevation for convenience in illustration.

Referring to the drawingpl represents a stock tank the tank illustratedbeing such as are commonly employed for rotary boilers ln paper mills. This tank is provided with end plates 2 and 2. The end plate 2' has a bracket 3 thereon: mounted on the pedestal 4, the end plate shes a bearing 5 thereon for the shaft 6 which projects through into the bearing 7 on the pedestals. A supporting pedestal 9'is disposed near the pedestal 8 to engage the under sideof the tank;

- A steampipe lOprojects into the tank to heat its contents, the pipe,beingperforated so'that theste'am is admitted directly to the tank, the perforations --not being illustrated as they will be readily understood.

loosely mounted so'that the material may escape over the upper edge of the chamber.

This top plate is h'eld under press'ure'by I means of the spring 23 an'd'the weight123,

"the springs beingarranged'on the guide rods 24 carried-by the top member 22 and arraI ged through holesin the top 35 of the housing 30.

The material is discharged into thewcha'niher from thenozzle 25 connected'to the discharge pipe 26 of the circulating pump 27.

The top member 22 is provided witha downturnedflange 28 at its outer edge so that the material is directed therefrom downwardly against the concave deflector member 29 'mounted on the outer side of the chamber 20. The housin'g'30 is mounted on the top of the-tank abovetheopening 31 so that "themat'erial is discharged back into the tank and'circalates therethr'oug'h-to the intake 32 of the This pipe has a discharge or draw-ofl connection 33'c0ntrolled by the three-Way valve 34.

With this arrangement of parts, the stock or material discharged from the nozzle 25 is whirled and agitated by the spiral within the disintegrating chamber and is discharged from'thetop thereof under the top or pressure plate which is sufiiciently weighted so that the desired pressure is maintained within the chambers; The material is discharged fromthe chamber onto the deflectorimember 29, and from thence into, the tank in which it is circulated asdescribed. The disintegrating of the stock is very efi'e'ctive and rapid and is without grinding or abrading action;

I have illustratedand described my improvements as adapted for use of'a rotary boiler: now. quite generally usedv in paper mills as a stock tank However, the tank may be greatly varied in shape and size as occasion requires. i I

I havenotattempted to illustrate and .describe various modifications and adaptations which I, contemplate as I believe the dis closure made will enable those skilled in the artto which my invention. relates to embody or adapt the same as maybe desired. Having thus describedmy invention, what I claimas new andv desire-to'secure by Letters Patent, is: V v 1.
